Current low power design and verification standard (IEEE 1801-2013 and IEEE P1801) is focused on the voltage distribution structure in design at Register Transfer Level (RTL) description and below. It has minimal abstraction for time (only interval function for modeling clock frequency), but depends on other hardware oriented standards to abstract events, scenarios, clock trees, etc. which are required for energy proportional design, verification, modeling and management of electronic systems. The necessary abstractions of hardware, as well as layers and interfaces in software are not yet defined by any existing standards. This standard addresses energy proportionality through tight interplay between energy-oriented hardware and energy-aware software. It provides new design, verification, modeling, management and testing abstractions and formats for hardware, software and systems to model energy proportionality, and enables the design methodology that naturally follows the top-down approach - from the system and software down to the hardware.
